Implementations

impl Viewport

pub fn new() -> Self

pub fn left_edge_time(self, num_timestamps: &BigInt) -> BigInt

pub fn right_edge_time(self, num_timestamps: &BigInt) -> BigInt

pub fn as_absolute_time( &self, x: f64, view_width: f32, num_timestamps: &BigInt, ) -> Absolute

pub fn as_time_bigint( &self, x: f32, view_width: f32, num_timestamps: &BigInt, ) -> BigInt

pub fn pixel_from_time( &self, time: &BigInt, view_width: f32, num_timestamps: &BigInt, ) -> f32

Computes which x-pixel corresponds to the specified time adduming the viewport is rendered into a viewport of view_width

pub fn pixel_from_absolute_time( &self, time: Absolute, view_width: f32, num_timestamps: &BigInt, ) -> f32

pub fn clip_to( &self, old_num_timestamps: &BigInt, new_num_timestamps: &BigInt, ) -> Viewport

Return new viewport for a different file length

Tries to keep the current zoom level and position. If zoom is not possible it will zoom in as much as needed to keep border margins. If the new waveform is too short, the viewport will be moved to the left as much as needed for the zoom level.

fn width(&self) -> Relative

fn width_absolute(&self, num_timestamps: &BigInt) -> Absolute

pub fn go_to_time(&mut self, center: &BigInt, num_timestamps: &BigInt)

pub fn zoom_to_fit(&mut self)

pub fn go_to_start(&mut self)

pub fn go_to_end(&mut self)

pub fn handle_canvas_zoom( &mut self, mouse_ptr_timestamp: Option<BigInt>, delta: f64, num_timestamps: &BigInt, )

pub fn handle_canvas_scroll(&mut self, deltay: f64)

fn set_viewport_to_clipped( &mut self, target_left: Relative, target_right: Relative, num_timestamps: &BigInt, )

fn set_viewport_to_clipped_no_width_check( &mut self, target_left: Relative, target_right: Relative, )

fn midpoint(&self) -> Relative

fn half_width(&self) -> Relative

fn half_width_absolute(&self, num_timestamps: &BigInt) -> Absolute

pub fn zoom_to_range( &mut self, left: &BigInt, right: &BigInt, num_timestamps: &BigInt, )

pub fn go_to_cursor_if_not_in_view( &mut self, cursor: &BigInt, num_timestamps: &BigInt, ) -> bool

pub fn is_moving(&self) -> bool
